This story was pretty dark most of the narrative. If you enjoy that type of story, this may be for you. The author did well with the historical Ohio setting. I've seen the cliffs along the Ohio River that she mentions. Ezra was probably the most interesting, but secondary, character. The problem is that Nathan has some intense negative feelings toward Weasel, and rightly so. The title character was an evil person who committed evil acts affecting all in the story. Nathan came to the conclusion that it was his duty to kill Weasel.
My main problem is that during the resolution of the story, Nathan never seemed to realize how his actions would have made him like Weasel. It's true, that his feelings changed toward the end of the book and he grew as a character, but it seemed like more of an accident. And I'm not sure if Nathan, at the end of the book, still wouldn't try to kill Weasel if he had the chance.
If you have similar thoughts, or you see Nathan's growth in a different way, please comment. I'm curious to see if I'm missing something or if others agree with me. Would Nathan at the end of the book still go after Weasel if he had the chance?
